I have just completed a new Motorcycle Choppers Gallery similar to one I had on the old site. Of course, its growth depends on you. If you own a chopper, send me a picture and description and I'll place it in the gallery. I also have an article, Choppers, that gives the history of the chopper.
I recently reviewed the newest book by the OCC guys, Orange County Choppers: The Tale of the Teutuls. It traces their rise from obscurity to the top of the custom chopper heap. Whether you like these guys or not, their book is interesting reading and may change a few opinions.
